I just bought a 580c and am trying to clean it up a little and get it operating a little smoother. One of the main problems I have is that a lot of the holes/pins between the levers and valves are really loose. The holes seem to be pretty elongated. Any ideas how to fix something like that? Thanks for the help
Drill them out and put in larger pins.... Weld up the holes and re-drill them.... Lots of options, just depends how bad they are.
Had the same issue on my Ford. I bought some bronze bushings (nylon would work too) from Tractor Supply and Lowes, drilled out the holes and slid in the bushings, reused the original pins. Problem solved. I should have taken pictures of the process but it was pretty simple and worked great!
